At the sides of the upper flight of the conveyer belt are arranged guide rails y 12 which together with the belt form a trough through which the rails are guided to the feed chains.

To adapt the feed chains to various thickness of sash rails they are laterally and relatively adjustable on the table or machine top, and the chains are also adjustable longitudinally rto compensate for wear and to secure the proper tension on the working flights.

Each feed chain is provided with a longitudinally extending frame or guide plate as 13 and 14, resting on the machine top 2. At their sides the respective plates are fashioned with upright flanges 15 for guiding the outer and inner flights of the chains, and on the bottom of each plate is a threaded boss 16 projecting `through a transversely extending slot 17 in the machine top beneath the plates. There are two bosses 16 on each plate spaced apart and the bosses on one plate are alined with the complementary bosses on the other plate as in Figs. 3 and tl in order that the relative position of the two feed chains may be correctly adjusted by manipulation of four screw bars 18. These bars are arranged transversely of the machine and chains in alined pairs and at their outer ends the bars have hand wheels 19 for turning them in their hearings 20 in the side flanges 21 of the machine top 2.

Each chain has a driving sprocket wheel as 22 and 23 on vertical feed shafts 24 and 25 journaled in bearings 26 of the machine frame, and these shafts are driven from a countershaft 27 through bevel gear couples 28. The countershaft 27 is'operated from the power shaft 3 by means hereinafter described.

vIdler sprockets 29 and 3() for the chains 8 and 9 are journaled in brackets 31 which are slotted at 32 and adjustably connected to the plates 13 and 14 by inea-ns'of the twopairs of bolts 33, audit will be apparent that the bearing brackets 3l of the wheels 29 and 30 may be adjusted relatively t0 the plates for tightening or loosening the chains 8 and 9 on their pairs of supporting sprocket wheels, and tocompensate for wear of'parts. Y

The two adjoining working flightS Of the chains grip the rails at opposite sides thereof and move in the same direction to pre-- sent an alined pair of rails R and lli to the relishing tools. The rails are fed in al row intermittently and two of the rails are relished by the machine tools while the rails are detained or at rest. The relishing tools reciprocate into and out of operative position synchronously with the feed movement of the rails. The rails are advanced by the fric-tional engagement therewith of the feed chains and are positively held on retained for the operation of the rclishing tools, while the feed chains continue .to move relatively to the rails. The friction between the chains and rails is sufficient to move the rails while they are free to advance, but the chains slide past the rails while the latter are detained. In their advance toward the relishing tools the rails R and R pass under and are held down on the machine top by means of a leaf or plate spring 34 attached to the upper frame 35 which is bolted on the top of the machine frame. Y

The relishing tools comprise a pair of spaced boring bits 36 and 37 and an intermediate rotary cutter head 38 arranged in a line parallel with the line of travel of the rails7 as indicated in Figure 6.

The relishing tools are located beneath n the machine top and the rails are moved across the machine top with their adjoining tenons T in position for operation thereon ofthe relishing tools, thecut away portion of the tenons being indiiatcd bydottcd lines in Figure 6 and in full lilies in Fig. Gf.

The rear rail R of a pair of rails is. positively detained or stopped with its tenon in position for action of the boring hit 3T and cutter head 3S and then the front rai] R is relatively advanced a distance as indicated in dotted lines in Figure 3 to bring the tenon of this rail in position for action of the boring bit 36 and cutter head 33.

F or detaining the rear rail R a laterally swinging or oscillatable detent 39 is acapted to engage the shoulder of the rail at the junction of the tenon and Arail and hold thc latter during the relishing operation, and after the operation the detent is swungr out of the path of the cut rail. `This dctent is carried by a longitudinally slidable rock shaft 40, and secured thereon in adjusted position by its sleeve l1 and set bolts 42. The rock shaft is elevated above the rails and journaled in bearingsk in flanges 43 of the upper frame 35, and` an expansion spring 44 coiled about the shaft is interposed between one of the flanges 43 and an anchoringpin l5 on theshaft. This spring serves the two functions of oscillating the to the left in Fig. 8 Vsaid tappet bolt coin s The eccentric link isalsoconnected by a tracts with the upper end of the locking le.

ver and swings said leverfto the left, Withdrawing hook 82 from the roller 83 to release the cross head and permit its upward movement to bringV the relishing tool in operative position with relation to the spaced.

' tion of a hand wheel 109 and'screiv bar 110 tenons ofthe sash rails.

The several shafts of the Vrelishing tool frame arervertically slidable in fixed journal bearings 87 of the rectangular. tool frame 80, and the shafts also'h'avea sliding movement inthe gears 88 89 and 90 respectively, which gears are keyed to revolve with their respective shafts 7 6 are in mesh at alltimes.

Power is transmitted to the shaft- 78 of the relishing tool frame from power shaft 3 by means. of a bevel gear 91 on the latter shaft and a pinion 92 on thefshaft 78 for revolving the three members. of the relishing tool.

The cross head 79 is 4vertically-v reciprocated to lift the relishing tool frame to operative position and to Withdraw the same from operative position, by power also transmitted from the shaft 3, through' pinion 93 on the latter shaft and a larger gear 94 on the clutch shaft 95`located above the power shaft 3 and parallel with .the latter. The clutch shaft is journaled in bearings 96 of the main frame and is providedavith a clutch 97 (Fig. 5) that is manually controlled through manipulation of either of the crank handles 98 or 99 atfthe ends of a crank shaft 100 disposed longitudinallyof the machine and supported in bearings in-the mainframe of the machine. The operation of the machine is thus manually controlled hy manipulation of either of these two crank handles. f 4 i Above the clutch shaft 95 is located an operating shaft 101 journaled in bearings 102 and provided with a large, loose sprocket Wheel 103 for the sprocket chain 104; A. friction clutch V105 on this shaft 101 permits free rotation' ofthe sprocket Wheel 103 While the hook`82 holds the lever 81 in locked re.- lation to the cross head. 'Vhen the lever is moved and the hook freedV from the roller to unlock the cross head the clutch engagesy with the sprocket wheel with sufiicientfriction to revolve the latter and the operating shaft 101 for the upward movement of the cross head 79 and its relishing tool.

The operating shaft 10.1 carries at one end a disk 102.k and rotary movement of the shaft and this-disk is converted into reciprocating movement of the cross head through the interposition of an eccentric 103 having a` pin'connection at 104; to the disk. rThe eccentric link is slotted .at 105 for varying the length of its'throiv or stroke.

pin as 106 to a lug 107 of the cross head, and

anarcuate slot 108 in thelink also provides 77 and 78 and.

(Figs. 1 and 2) which latter is connected at 111 to the eccentric link, and in this mannei' the relish ,i of the tenons T indicated by dotted lines in Fig. 6 maybe predetermined4 andfixed. n p

The push lever t9 is actuated from shaft and a cam lug 50 carried at the lower free end ofthe lever co-acts with the regulatinr disk to siving the lever on its pivot 50 anf push the slidevplate or tappet plate 46 as previously described.

r1`he sprocket chain 105 as seen in Figure 1 is driven from the shaft 95 by means` of a sprocket Wheel 112.011 said shaft, and this chain is provided with a double loop, one of which passes around a sprocket Wheel 113 on the shaft 27 to actuate the feed chains 8y and 9. Another loop ofthis'sprocket chain passes around afsprocket VWheel 114 on the shaft 115 located at the opposite side ofthe wheel112. rEhis horizontal shaft 115 has a bevel gear couple 116 .for transmitting pou'ertothe vertical cam shaft 60.

4'Iheconve'yer belt 10 is driven from the shaft 27 by means of a pulley 117 on the latter shaft, and a crossed `belt 118 and pulrley 119 onthe shaft120.

After the adjoining tenons of the pair of sash rails have been relished by the operation of the machine tools the completed rails are discharged at the rear end of the machine, i. e. at the right in Figs. 1 and As they are discharged through the pushing action 101 by means of a cam disk l19 on this shaft of sash rails. The spring 122 at the Side-120 Vof the sash rail opposite to the guide rail is carried by an adjustable slotted bar 126 which isy retained on the machine to) by bolts 127. VFhe spring thus` provides j or a resilient pressure against thesash rail to hold it against the guide rail, and the ten sion of thespring againstthe rail may be varied by manipulating a hand Wheel and screw bar 1285to move the slotted bar 126 transversely of the'machine top.
